1. Material selection
The greenness of the mold material has a very important impact on the green performance of the final product. The choice of materials for green design must be based on green materials, abandoning the chemical methods used to surface the materials in the past, and replacing them with physical methods to achieve corrosion protection or easy release. Choose high-quality mirror mold steel to process mold cavities; use stainless steel to process anti-corrosion molds instead of electroplating; or replace electroplating with nickel-phosphorus plating that is less harmful to the environment.
The basic properties that green materials should have are:
(1) Low pollution, low energy consumption and low cost;
(2) No pollution or less pollution during easy processing and processing;
(3) Degradable and reusable.
2. Design standardization and standardization
Mold standardization is the prerequisite for the professional production of molds. The professional production of molds is the key to improving mold quality, mold manufacturing cycle and cost reduction.
Adopt and purchase standard formwork and other standard parts. The mold base and standard parts are produced by specialized manufacturers and enterprises through social division of labor, so that limited resources are optimally configured. Molds are usually only used after scrapping, but the formwork is still completely intact, so the use of standard formwork helps the formwork to be reused.
There are many types of molds for stamping and injection molding, and these mold bases are basically composed of standard upper and lower mold bases, guide posts and guide sleeves. At the same time, the standardization of the formwork can greatly reduce the equipment used to produce the formwork, thereby saving resources. Also good for management. Standardization and standardization of each structural unit of the mold. This speeds up design, shortens design cycles, and facilitates process management.
